AS Level Chemistry - Unit 7.2 Brønsted–Lowry theory of acids and bases

**This Powerpoint specifically uses the Cambridge AS Level Chemistry Syllabus (9701) and covers all criteria for – Unit 7.2 Brønsted–Lowry theory of acids and bases
**

Students will be able to -

1 state the names and formulas of the common acids, limited to hydrochloric acid, HCl, sulfuric acid,
H
2SO4, nitric acid, HNO3, ethanoic acid, CH3COOH

2 state the names and formulas of the common alkalis, limited to sodium hydroxide, NaOH, potassium hydroxide, KOH, ammonia, NH3

3 describe the Brønsted–Lowry theory of acids and bases

4 describe strong acids and strong bases as fully dissociated in aqueous solution and weak acids and weak bases as partially dissociated in aqueous solution

5 appreciate that water has pH of 7, acid solutions pH of below 7 and alkaline solutions pH of above 7

6 explain qualitatively the differences in behaviour between strong and weak acids including the reaction with a reactive metal and difference in pH values by use of a pH meter, universal indicator or conductivity

7 understand that neutralisation reactions occur when H+(aq) and OH–(aq) form H2O(l)

8 understand that salts are formed in neutralisation reactions

9 sketch the pH titration curves of titrations using combinations of strong and weak acids with strong and weak alkalis

10 select suitable indicators for acid-alkali titrations, given appropriate data (pKa values will not be used)

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a free pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
